Abstract

The utility model relates to a device for accurately measuring a die cavity of a cast. The device comprises an n-shaped sample plate, wherein the bottom surfaces of two ends of the n-shaped sample plate are positioned on the same horizontal plane, and the thickness D of the n-shaped sample plate is 5-10mm; and the gap W between the two ends of the n-shaped sample plate is 10-20mm. The device for accurately measuring the die cavity of the cast has the advantages of being simple in structure, simple and convenient to operate, being made of wood or glass fiber reinforced plastic material, reducing the manufacturing cost, being capable of measuring the wall thickness before box closing, reducing the box covering processes, reducing the operation steps, improving the quality of the cast and improving the production efficiency.

Description

A kind of device of accurate measurement foundry goods die cavity

Technical field

The present invention relates to a kind of device of accurate measurement foundry goods die cavity.

Background technology

The foundry goods of producing in batches has remarkable advantages than the single-piece production foundry goods: reduce the iterative process design, die model is reusable, casting quality is stable, workman's skilled operation, easily constitute the production line manufacturing.

Heavy castings for hand moulding, following core, the shape relative complex of some core, size is various, special-shaped spot size is difficult to measure in the actual production process, be difficult to record casting section thickness before the mould assembling of branch mailbox moulding castings, wall thickness deviation appears in foundry goods behind the moulding by casting easily, increases the probability that there are potential quality problems in foundry goods.And the foundry goods of producing in batches needed measure each foundry goods repeatedly, increased workman's workload, reduce production efficiency.

Summary of the invention

For overcoming the deficiencies in the prior art, the purpose of this utility model provides a kind of device of accurate measurement foundry goods die cavity, can speed accurately measure the foundry goods cavity dimension before mould assembling, and is simple to operate.

For achieving the above object, the utility model is achieved through the following technical solutions:

A kind of device of accurate measurement foundry goods die cavity comprises a font model, and described door bottom surface, font model two ends is on the same horizontal plane, and described door font model thickness is D=5-10mm; The gap between two ends of described door font model is W=10-20mm.

Compared with prior art, the beneficial effects of the utility model are:

Simple in structure, easy and simple to handle, make with wooden or glass-reinforced plastic material, reduce cost of manufacture, but wall-thickness measurement reduces the case process of covering before the mould assembling, reduce operating procedure, improve casting quality, enhance productivity.

Structural representation when Fig. 3 is the utility model work.

Among the figure: 1-door font model 2-core 3-die joint 4-sand mold.

The specific embodiment

Below in conjunction with Figure of description the utility model is described in detail, but should be noted that enforcement of the present utility model is not limited to following embodiment.

See Fig. 1-Fig. 3, a kind of device of accurate measurement foundry goods die cavity comprises a font model 1, and described door bottom surface, font model 1 two ends is on the same horizontal plane, and described door font model 1 thickness is D=5-10mm; The gap between two ends of described door font model 1 is W=10-20mm.

Embodiment:

Adopt hard materials such as wooden or fiberglass to make during making, the sandbox die joint is the plane.

According to different size core 2, make the door font model 1 of differing heights, making door font model 1 needs with hard materials such as steel plate or fiberglass, and model thickness D is about 5-10mm.

After core 2 is put into sand mold 4 die cavities, the door font model 1 of correspondingly-sized is placed on (as shown in Figure 2) on the nowel die joint 3, measures plane separation door font model 1 short transverse distance on the core 2, whether satisfy the drawing requirement thereby before mould assembling, record casting section thickness.Carry out multimetering, guarantee that core 2 is steady.

The core 2 of differing heights needs the door font model 1 with different size.Last nowel die joint 3 assurance levels guarantee door font model 1 benchmark.Door font model 1 both sides are gapped apart from core 2, avoid scratching in the measuring process core 2.

The utility model is simple in structure, and is easy and simple to handle, makes with wooden or glass-reinforced plastic material, reduce cost of manufacture, but wall-thickness measurement reduces the case process of covering before the mould assembling, reduces operating procedure, improves casting quality, enhances productivity.

Claims
